WebCell Division Cycle-25 (CDC25) plays an important role in transitions between cell-cycle phases by dephosphorylating and activating CDKs. CDC25B and CDC25C play a major role in G2/M progression, whereas CDC25A assists in G1/S transition. Different isomers of CDC25 expressions are upregulated in various clinicopathological situations. Cdc25 activates cyclin dependent kinases by removing phosphate from residues in the Cdk active site. In turn, the phosphorylation by M-Cdk (a complex of Cdk1 and cyclin B) activates Cdc25. Together with Wee1, M-Cdk activation is switch-like. The switch-like behavior forces entry into mitosis to be quick and … See more The structure of Cdc25 proteins can be divided into two main regions: the N-terminal region, which is highly divergent and contains sites for its phosphorylation and ubiquitination, which regulate the phosphatase activity; … See more The Cdc25s, and in particular Cdc25A and Cdc25B, are proto-oncogenes in humans and have been shown to be overexpressed in a number of cancers. The central role of Cdc25s in the cell cycle has garnered them considerable attention … See more Cdc25 enzymes are well conserved through evolution, and have been isolated from fungi such as yeasts as well as all metazoans examined … See more Although the highly conserved nature of the Cdc25s implies an important role in cell physiology, Cdc25B and Cdc25C knockout mice (both … See more WebThis active phosphatase dephosphorylates Thr138 and holds Cdc25 in an inactive state until replication has been successfully completed and/or any DNA damage has been repaired. At this point, Chk1 activity wanes and dephosphorylation of Thr138 by PP2A/B56δ diminishes, allowing constitutive Cdk2 activity to predominate and phospho-T138 to ... chiny a ue handel
